Ten car-bomb explosions killed at least 39 people across the Iraqi capital on Monday, police and medical sources said.

In the central district of Karada, two parked car bombs went off killing at least eight people, and another two car bombs exploded simultaneously near a market in the western district of Jihad, killing eight. The deadliest attack came at night in Baghdad, when a car bomb exploded near a supermarket on a main commercial street in the Karrada neighborhood, killing five people and wounding 16.

Just after sunset, police said a car bomb went off near an outdoor market in the Shia suburb of Nahrawan, killing four civilians and wounding 15 others.

Minutes later, a car bomb went off near a market in the Shia-majority neighbourhood of New Baghdad. Police said that three people were killed and 10 others were wounded. Minutes later, a second car bomb hit a bus stop in the same neighbourhood, killing two people and wounding eight others.

Also, two people were killed in a car explosion in the Christian-Shia neighborhood of Garage Al Amana in southeastern Baghdad.

In the morning, a provincial police officer in Ninevah said a suicide attacker rammed his explosives-laden car into an army patrol in the city of Mosul, killing a soldier and a police officer. He said that seven people, including two civilians, were wounded. Mosul is 360km northwest of Baghdad.

Another officer said a second bomber blew his explosive-rigged belt inside a university campus in the city of Tikrit, killing a police officer.

Two medical officials confirmed casualty figures. All spoke anonymously as they were not authorised to release information to reporters.

There was no immediate claim of responsibility, but security forces and Shia residents are frequently targeted by Al Qaeda’s Iraq branch.
